I'm in a very contradictory camp of, at first, on say some new measure of some sort being propose, I'd probably be like "Well, you have no reason to worry if you have nothing to hide"... until I end up being the group they're watching XD Even if I have nothing to hide.

The police (broad-term) should go back to full-fledged policing and detective work. Surveillance and waiting catch someone in the act is not really how they're supposed to go about it.
